Using an OBD-II Splitter to Connect Two Devices (Fuel Economy Guage & Zubie)

Standard

I’ve added a couple of posts about the fuel economy guage recently but in those posts I left out the fact that I already had one device on the ODB-II port of my 2008 Chevrolet Impala – a Zubie vehicle monitoring device that is cloud-connected via its own celluar connection (the one at this link is slightly different from the ones that we have; they are both white and were also purchased as a two-pack – I don’t know if there is any technical difference between the models).

In order to solve this issue I decided to purchase a iKKEGOL 30cm/12″ ODB2 ODB II Splitter Extension Y J1962 16 Pin Cable Male to Dual Female Cord Adapter. I’m not sure why the item name is written as ODB2 ODB II as it should instead be OBD2 OBD II but it does work properly. I read several reviews before deciding to purchase this devices as I was uncertain whether or not having two devices connected in this way would cause issues. I decided that it was not very likely to be a problem because the fuel economy guage only reads from the system and the Zubie device probably rarely ever sends data, if at all.

I haven’t had a single problem with either device since I connected them to the splitter.

The white fabric is actually an elastic material helping to ensure that the connection to the OBD-II port doesn’t slip loose. Normally, the cables are tucked away better but I had just shifted them before taking this cable to reposition the fuel economy guage.

Reducing Windshield Reflection of an Auto Meter 9105 ecometer Fuel Consumption Gauge Display

Standard

The Auto Meter 9105 ecometer Fuel Consumption Gauge works great but when driving at night I started to experience a slightly distracting problem. A reflection of the guage’s display was very visible higher up the windshield. This was probably aggravated by the fact that I have it placed directly on my dash, which curves up and thus causes the guage to be at more of an angle than if it was sitting flat.

I’ve managed to reduce the amount that is reflected, and could eliminate it further with a small modification, by building an extension of the guage’s hood. I lucked out and was able to find some black vinyl just sitting around (I originally asked a friend if he had some black construction paper but he had something better – vinyl), which I affixed to the hood of the guage with electrical tape to extend it out. This little trick seems to have been a significant improvement when driving at night.

Using an Auto Meter 9105 Ecometer to Improve Fuel Economy of a 2008 Chevy Impala

Standard

Ecometer.jpg

Back in December my commute to work changed from about 15-20 minutes one way to one hour to an hour and fifteen minutes. This significant addition of mileage drove me (no pun intended) to make minor modifications to my vehicle and driving habits to improve my fuel economy. In the beginning I used my vehicle’s built-in Instant MPG data to adjust my coasting and acceleration.

This small move did show an improvement in fuel economy but the digital guage isn’t well placed for frequent checks. I decided to purchase something that was much more obvious as it could be mounted directly onto my dash.

I’ve been using an Auto Meter 9105 ecometer Fuel Consumption Gauge, which costs around $100, and connects directly to the OBD-II port of my vehicle. Not only does it present the data in a much easier format to quickly glance at but I’ve also discovered that the referesh of the data is much faster than that of the built-in guage.

I’d prefer that the display could be dimmed significantly but otherwise it’s nearly perfect. If I’m applying several basic hypermiling habits I can indeed improve fuel economy. My vehicle’s highest MPG rating (highway) is 29 MPG but I’ve been able to achieve 30.29 MPG once and most of the time I hit between 26 and 28 MPG unless I’ve had a lot of in-city driving in my car. I have more MPG data from this year that I may share in a later post.

The guage by itself does nothing to improve fuel economy but it provides the ability to make driving decisions quickly, potentially saving fuel.

Easy Accessory Power Switch for a 2008 Chevrolet Impala

Standard

I used a dashcam, phone charger and bluetooth adapter in the car for a while but I grew tired of having to manually unplug those devices when not in use or when I turned the car off. Unfortunately, in my 2008 Chevrolet Impala the vehicle would continue to provide power to any plugged in accessories even when the engine was off. Most of these devices are low power but even a dashcam, given enough time, could eventually drain the vehicle batter, especially if the car wasn’t being used for several days.

Re-wiring the electrical system and messing with fuses is beyond my experience so I decided to see if I could find an automotive power strip that would have a built-in power switch and sure enough I was able to find the perfect device.

The EUGIZMO Cigarette Lighter Splitter only costs about $16, offers three DC outlets, four USB power ports, a large power switch for the unit and also a very good visual indicator to show whether or not it is on.

I chose to mount this upside-down, just below the vehicle’s built-in DC power ports. This placement moves most of the power adapters and cables out of the way; whenever I turn the car on or off it’s very easy to just reach down and hit the large power button.

At first affixing the unit beneath the dash was a bit of the problem as the first type of velcro that I had used simply wasn’t holding and it would often come loose during the day. Eventually I ended up using some VELCRO Exterme Outdoor Strips and it hasn’t come loose since.

Accessing a Remote Network with a TP-Link SafeStream TL-ER604W Router

Standard

Back in December I started using a TP-Link SafeStream TL-R600VPN Gigabit Broadband Desktop VPN Router to be able to login to the network at a remote property. It provided most of the functions I needed but unfortunately the client/server mode of the VPN service only supported PPTP. While not every secure it would have been fine for my purposes but unfortunately Apple dropped support for PPTP VPN connections from the newer Mac OS and iOS versions. I was able to purchase a program called Shimo to use PPTP from the Mac but there wasn’t really a good solution for iOS and being able to access the network from my phone was a critical need.

Frustrated that I couldn’t use my phone to connect to the network I eventually purchased a TP-Link SafeStream TL-ER604W Wireless N300 Gigabit Broadband Desktop VPN Router, which provides PPTP, L2TP and IPSEC client/server connections and so far it has worked great.

Both routers have, on at least one or two occasions, each hung up and required a manual power reset. The NetReset device I purchased recently seems to have eliminated that infrequent problem.

Using an Aeotec Smart Strip

Standard

SmartStrip01

A while back I decided that it would be nice to have our son’s bedroom lamp, white noise machine and humidifier all plugged into Z-Wave automation switches. But I no longer had any free modules and this meant that I’d need to purchase three Z-Wave plug-in modules. That’s not a small cost and would require more room than was available at the outlet or involve a very ugly set of power cables.

To resolve this problem, and also reduce cost, I decided to purchase an Aeotec DSC11 Smart Power Strip. This power strip provides six power outlets with four of them controllable using Z-Wave. The four can also be controlled as a single unit to turn all of them on or off.

SmartStrip02

This turned out to work well. I have it connected to my Indigo software and also an Aeon Labs Minimote. On the Minimote one button controls only the lamp and another controlls the noise machine and humidifier as a group.

I haven’t had any problems with this device.

Using Indigo 7 for Home Automation with a Mac

Standard

Back in 2013 I moved from using a very good Windows program called mControl for home automation control over to Indigo for Mac OS. mControl worked great for my needs then but I didn’t want to dedicate an additional computer to the home automation and video recording tasks since I usually left my iMac running anyway.

Indigo looked like an excellent choice and over the years and it has indeed proven to be a great software package for home automation control from a Mac. I realized that even though I’ve blogged about some of the things that I’ve done with Indigo I haven’t really mentioned my overall experience with the software.

It’s now on version 7 and though the cost has risen this is largely due to improved software support and the inclusion of the required licensed technology needed to control Z-Wave compatible door locks. Indigo is very extensible; one can find a number of community-built plugins and it also supports scripting via Python.

I wouldn’t recommend it for someone that isn’t very tech savvy; there are other consumer appliances more suitable for basic home usage, but if you want to do anything more than have a few automated tasks (for example, anything that requires a good bit of logic and virtual devices or variables) you’ll need something like Indigo.

At our house I do use a Wink system and it works fine there but it’s not capable of doing much more than running a few automated tasks; consumer appliances (usually cloud-connected) currently don’t offer very much in this realm. But at the apartment I’m still using Indigo and have moved into some more advanced home automation interactions.

With Indigo I now have several actions that are dependent on the status of other devices, virtual devices and variables. I’m also using some Bluetooth proximity detectors to provide additional enhancements and in the past I’ve done some more interesting things that I currently don’t have setup.

I highly encourage anyone with more than a passing interest in home automation, and a Mac that you’re willing to leave powered on all of the time, to look into Indigo. The initial cost may seem high but when you consider the basic cost just to purchase a consumer appliance hub such as Wink or SmartThings, and then potential issues with any of your existing equipment, you may find that the savings aren’t really there in the long run. Indigo works with X10, Insteaon and Z-Wave devices as well as some other devices that don’t use those protocols.
